The expansion card can be installed in any one of the SLOT1, SLOT2, and SLOT3 card

slots.
The VFD models of 7R5P and lower can be configured with two expansion cards at the

same time, and those of 011P and higher can be configured with three expansion cards.
If interference occurs on the external wires after expansion cards are installed, change

their installation card slots flexibly to facilitate the wiring. For example, the connector of
the connection cable of the DP card is large, so it is recommended to be installed in the
SLOT1 card slot.
To ensure high anti-interference capability in closed-loop control, you need to use a

shielding wire in the encoder cable and ground the two ends of the shielding wire, that
is, connect the shielding layer to the housing of the motor on the motor side, and
connect the shielding layer to the PE terminal on the PG card side.
The following figure shows the installation diagram and the VFD with expansion cards
installed.
